BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oilin the

an_rle.

• Be sure mower is ievel and area around oil

fillis dean.

•Remove engine oil cap w/dipstick and fillto

the full line on _%edipstick.

•Use20ozs. of oil. For type and grade of oil

to use, see "ENGINE" in Maintenance

section of this manual.

•Pour oil slowly. Do not overfill.

•Check oil level before each use. Add oilif

needed. Fillto full lineon dipstick.

•To read proper level, tighten engine oilcap

each time.

•Reinstall engine oilcap and tighten.

•Change the oil after every 25 hours of

operation or each season. You may need

to change the oilmore often under dusty,

dirtyconditions.

GAS

•Fill fuel tank. Use fresh, clean, regular

unleaded gasoline with a minimum of 87

octane. (Use of leaded gasoline will

increase carbon and lead oxide deposits

and reduce valve life). Do not mix oil

with gasoline. Purchase fuel in quanti-

ties that can be used within 30 days to

assure fuel freshness.

IMPORTANT: WHEN OPERATING IN

TEMPERATURES BELOW 32°F(0°C), use

fresh, clean winter grade gasoline to help

insure good cold weather starting.

WARNING: Experience indicates that

alcohol blended fuels (called gasohol or

using ethanol or methanol) can attract

moisture which leads to separation and

formation of acids during storage. Acidic

gas can damage the fuel system of an

engine while in storage. To avoid engine

problems, the fuel system should be

emptied before storage of 30 days or

longer. Drain the gas tank, start the

engine and let it run until the fuel lines and

carburetor are empty. Use fresh fuel next

season. See Storage Instructions for

.additional information. Never use engine

or carburetor cleaner products in the fuel

tank or permanent damage may occur.

CAUTION: Fill to bottom of gas tank filler

neck. Do not overfill. Wipe off any spilled

oil or fuel. Do not store, spill or use

gasoline near an open flame. Gasoline filler

•Turn electric start key clockwise to crank

engine.

IMPORTANT: Do not crank engine more

than five continuous seconds between

Exchange the use of the start key for

starter handle. Pull starter handle

quickly. Do not allow starter rope to

snap back.

•To stop engine, release operator

presence control bar.

NOTE: In cooler weather it may be

necessary to repeat priming steps. In
